    Hi Rami, I’m wondering if you can help this enthusiast understand how you find the exact coordinates for a point for the base station or a total station when needed. It seems to me many total station operations you need exact coordinates of a point and for the base station you also need exact coordinates. It seems to me it’s a bit like the chicken and the egg situation. How do you find that exact coordinates of that first point? I’m from the U.K. not the US if that changes anything.
    Thank you.

    • @Richard_GIS
      @Richard_GIS 2 роки тому

      Most governments have an open data portal or map where you can normally activate and deactivate layers, there should be all points (at least that one from the governments). Have a look for example in www data gov uk (urls do not work in yt), sometimes it also helps to go for a city data portal - or just ask a local surveyor

    Great video! However, will the base lose its mobile connection when you're out in the field collecting coordinates with the rover? Basically will the hotspot range be a limitation, unless you have two smartphones to leave with the base and one to collect data on the rover?

    • @islandsurveyor
      @islandsurveyor 2 роки тому

      Good day. With these receivers, the base will not be transmitting corrections via wifi. The corrections will be transmitted via built-in uhf radio (Lo-Ra) or the internet. If the latter is used then both the base & rover will need 2 separate connections to the internet. So the short answer is no - the hotspot range will not be a limitation

    • @islandsurveyor
      @islandsurveyor 2 роки тому +1

      The point will have to be calibrated from a known point either by observing a known point nearby or connecting to a network of receiver(s) such as VRS or NTRIP.

  • @MatthewIvers

    • @samrajdwivedi
      @samrajdwivedi 3 роки тому +1

      Depending on your location, you might find a geo-referenced point from hydrology department of your area, land survey companies near your location or a GTS benchmark. You can then use the baseline transfer to geo-reference your nearby point from the already existing geo-referenced point ( legs of transfer depend on the distance between both the points)

    I have a question regarding disturbances. Since you have a relative position to the base station, does this allow you to have a better fix with heavy obstructions overhead? For example under an overpass or similar.

    • @RamiTamimi
      @RamiTamimi  3 роки тому +5

      Not really, both the rover and the base are observing satellites, so if either one of them is obstructed, you will not have a fixed solution.

Do you have any videos on how to diagnose when your Base and Rover recievers lose fixed connection intermittently? For example, how do you know when it can be a simple fix like changing the frequencies or something where the only way to achive fix is to switch from Lora to NTRIP?

    I’m struggling to understand just one thing… How could you know the coordenate of this point that you setup your base station if you “rent or buy” the RTK just for that reason? In my case i picked up some points using a total station, so the only reason im renting an RTK GPS is to reference a materialized point that i used as a base point for the total station.
    I know that in someplaces you have a geodesic mark, a fisical mark, that has already known coordinates. But in a case that you don’t have this, can you just set up your base station anywhere you want and start yours measurements? I hope you understand my question, English is not my home language 😂 thanks for now

    how do you determine the lattitude and altitude of base with high accuracy? i suppose the value you can read from google map is not that accurate because it is based on GPS which has an error of meters.

    Rami love your channel. I am new to surveying. I just go into the surveyors unions out in NYC. I start my CST class in October. I have a question about this particular setup I will try to make it not sound so confusing. I work for a construction company. We currently sun out all the survey work, they get the plans from the engineers and then they lay out the job site with a total station. I have a set of plans for myself and I use an automatic level to shoot grades they lay out for me. On the plans they have a section that has all known points and traverses with elevations, coordinates etc. if I were to get this particular unit you use and I set up the base station on known points, input the coordinates will I at least have the correct elevations? I know that I won’t have the layout of the job on there but at least having the elevations will help so I can walk the job site and check elevations on the road, manhole castings etc. it would be easier then setting up a level, and trying to mathematically figure out the elevations. Second question. Is there a way to import the engineers layout onto the app so I could layout a job site (drainage manholes, curb sidewalk etc) using this unit instead of a total station? Hope I didn’t confuse you.
